Abstract
Water stress can be induced in plant tissues, directly or indirectly, by a number of environmental conditions. Plants exposed to drought, heat, cold, wind, flooding, or saline conditions often synthesize foliar anthocyanins in response. Although previously thought to function as a UV screen, anthocyanins may instead serve to decrease leaf osmotic potential. The resulting depression of leaf water potential could increase water uptake and/or reduce transpirational losses. Combined with other anti-stress activities attributed to anthocyanins (including their solar shield and antioxidative capacities), this phenomenon may allow anthocyanin-containing leaves to tolerate suboptimal water levels. The often transitory nature of foliar anthocyanin accumulation may allow plants to respond quickly and temporarily to environmental variability rather than through more permanent anatomical or morphological modifications.
